Dinosaur feathers ‘developed for courtship’

25th October, 2012

Fossils found in Canada suggest that wings evolved in Dinosaurs earlier than thought.

The newly discovered specimens  show an overall covering of downy feathers but only the adults display wing-like structures with much longer feathers, suggesting  they may have developed for mating and display purposes later in life.

This combined with the size of these dinosaurs indicates that wings did not initially evolve for flight.
